The state of equilibrium can be expressed as a ratio, known as the equilibrium constant (K_eq), which relates the concentrations of the reactants and products at equilibrium. This does not imply equal amounts of matter on each side, nor does it directly relate to the activation energy, which is the energy required to initiate the reaction, not to reach equilibrium.
